COOKING STOVE OR RANGE.

SPECIFCATION forming part of Letters Batent No. 693,343, dated Februaryl1, 1902. Application filed December 13, 1900. Serial No. 39,687. (Nomodel.)

To all w/tom 'it may concern:

Be it known that I, EDGAR W. ANTHONY, a citizen of the United States,residing at Brookline, in the county of Norfolk and State ofMassachusetts, have invented a new and useful Improvement in CookingStoves or Ranges, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart 1o of this specification, in explaining its nature.

Figure l is a view in vertical section of a' range havingthe features ofmy invention.

upon the dotted line l l of Fig. 2, also showzo ing in elevation theparts of the range back 3o ranges.

4o right angle to the Walls.

of said line. Fig. 2 is a vewof the range in cross-section upon thedotted line 2 2 of Fig. l. Fig. 3 is a view of the range in horizontalsection upon the dotted Yline 4 Al of Fig. l. Figs. 4, 5, and 6represent the hearth-plate and its riln or band.

The cooking stove or range has the ash-pit A,the fire-pot B, and`ordinary dues cornmon to the usual types of cooking stoves or Thebottom, top, and side walls of the baking-oven O are made of sheetmetal, preferably in one piece. This produces a box-like structure openat both ends. It is attached to the stove or range in the followingmanner: One end is riveted to the flange c of the oven-door frame c,thedoor-framebeing itself bolted or riveted in place to the side plate ofthe range. vThe inner end of the side walls has lugs or ears c2, whichextend at a These lugs or ears preferably are of cast-iron and formedintegral with the plates O O2, hereinafter referred to. The lugs or earshave holes through which are bolts or screws c3, extending through theside plate o* of the stove. The side plate c is formed, as representedin Fig. 3, to provide a shallow chamber c5 on its inner side, having theinclined or tapering edge or wall c6. The inner end of the sheet-metalwalls is a little larger in size than the inner end of `not rust ortarnish under any condition.

The bolts or screws' engaging the lugs or ears serve when tightened todraw toward the side plate o4 of the stove and into the shallow chamberthe inner corners of the oven-walls against the inclined wall c ofthe'side plate, causing thc corners of the oven-walls to conform to andtightly hug or bear against the inclined wall to such an extent as tomake a sufficiently tight joint between the inner edge of the oven-wallsand the side plate ol' the stove. The door-frame c' is at the same timedrawn by the screws or bolts c3 to its seat against the side frame oftherange. The lugs or ears c2 serve to receive the oven end plate D and tohold it separated from the side plate c4' sufficiently to create a deadair space c7 between it and the side plate. The side platelnay also belined orcovered upon its inside with a sheet or layer of asbestos papercl or other non-heat-conducting material, and the dead-air space c andheatdeadening 'layer prevent conduction of heat from the oven throughthe side plate of the stove. The metal plate D, which forms the innerend of the'oven, is fastened at one end by the lugs d, extending fromthe plate, and at the other end by a tap-screw d2, which screws into oneof the ears or lugs c2. This end plate D preferably has its out orexposed sidelined or surfaced with porcelain or similar material toprovide a whitepolished illuminating-surface to reflect forward the heatof the ovenin the oven-chamber and to disseminate and reect intheoven-chamber the light striking against it when the oven-door is open,so that the backpart of the oven is made attractive and visible and theend provided with a clean white finish which will The plates O C2 arecast-metal plates andare riveted or otherwise attached to thesheet-metal walls ot' the oven, and they are provided with ears orledges for supporting an oven-shelf.

The plate O is also a fine-forming plate, and

it is attached by its outer end to the flanges cand o8 of the oven-doorframe c. (See Fig. 2.)

Between the side wall e of the oven and the rear wall e of the ash-pitthere is an air-flue IOO ing through the bottom of the range. (See l`igs. l and 3.) The said air-flue E is connected, by means of holes einthe side wall e, with an air-circulating flue or passage el within theoven, formed by the castanetalplate C'. 'lhis plate C is of an angularshape-that is, it is formed to cover a large section of the side walland of the top of the oven-and it is connected with the oven by theopening e5 along its lower edge, and it opens into the oven by an outlete at its rear end. The plate is further fashioned to provide anenlargement e7 of the line or passage e* by being bowed outward into theoven, and this bowed portion of the plate covers a considerable part ofthe upper central area of the side wall e. This increases the width ofthe (lue or passage against the portion of the wall of the oven which ismost liable to become overheated and provides a larger air circulationagainst this portion of the wall, and thus tends to prevent theoverheating ot the plate e from overheating the oven. The operation ofthis part of the invention is as follows: Airis drawn into the iiue Ethrough inlets and passes into the oven circulating ilue or passage c"and through this passage about one side and a larger portion of the topof the oven to the on tiet e, where it enters the oven. As the ilue orpassage e4 also has an inlet el from the oven, it follows that thecirculation it provides not only supplies `the oven with fresh air ofuniform temperature, but also establishes a circulation through the ovenby causing air to be drawn from the oven through the inlet e5 and to bemixed with the atmospheric airas it enters and passes through the flueel. The flue e4 establishes an airspace at the side of the oven towardthe [ire-pot and. at the top of the oven, which serves, in addition toits functions as a source of supply of fresh air to the oven as acirculating agent, to prevent the overheating of the oven by checkingthe conduction of heat from the side wall and top of the oven. Thecastmetal plate C may have one or more small holes e* opposite theinlet-holes e3 through the flue e4, through which air from the oven mayenter the passage, and there may also be one or more vent-holes e in theback plate opening into the back flue.

I have shown in Fig. 2 a shelf construction comprising a shelf F, havingan extension which is therein indicated in dotted and full lines. Thisconstruction I do not describe in this application, as it forms part ofmy application for Letters Patent of the United States, Serial No.72,867, filed August 22, 1901.

I have shown in Figs. 4, 5, and 6 a construction of a band or rim which,while as shown it is applied to a hearth, may be applied to astove-plate or other like portion of a stove. I will describe it here,however, as applied to a hearthband for purposes of convenience merely.lleretofore hearth-bands have been made in two parts, which abut at ornear the front corner oi' the hearth andform a straight joint,indicating at once that the band or rim had been formed of two pieces.This is ob jeetionable because of this appearance and because the jointcollects dust and other inatter. 3y my improvement, while the l1earthband is still made in two pieces, it has the appearance of beingcontinuous or in one piece.

"This result is obtained by causing the corner end 7i of one section Ilto be shaped alongits outer end and to have its top adjacent to said endso formed as to provide a portion of a design 7L and also by fashioningthe abuttingend h2 of the other section H of the band to form a part ofthe entire design, the edge of which section H', with the edge of thecorner h, constituting a line 71.3 of the design. The said end of thesecond section may servo to secure the corner of the first section inplace to the stove by being shaped to form a stinken recess or supportunder which a lip h4 may extend or lap.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United Statesl. In a cooking stove or range, aside plate having a shallow chamber upon its inner side provided withinclined walls with a sheetmetal oven having a bottom, top and sides andopen at its back, slightly larger than the inner end of said chamber andof a shape to lit into the same, and connections between said side plateand the oven for drawing the sheet-metal oven into said chamber untilits inner edge or portions thereof are brought into close contact withthe inclined walls of the chamber, as and for the purposes set forth.
